In Geoengineering Study @NASciences Sees Merit in CO2 Removal, Risk in Reflecting Sunlight No sub. for m…

There is no substitute for dramatic reductions in greenhouse gas emissions to mitigate the negative consequences of climate change, a National Research Council committee concluded in a two-volume evaluation of proposed climate-intervention techniques. Strategies to remove carbon dioxide from the atmosphere are limited by cost and technological immaturity, but they could contribute to a broader portfolio of climate change responses with further research and development. Albedo-modification technologies, which aim to increase the ability of Earth or clouds to reflect incoming sunlight, pose considerable risks and should not be deployed at this time. Carbon dioxide removal and albedo-modification techniques have been grouped up to now under the common term “geoengineering,” but they vary widely with respect to environmental risks, socio-economic impacts, cost, and research ne...
